LOADING APPLIANCE.

Application filed November 10, 1921. Serial No. 514,125.

To all whom, it concern:

Be it known thatI, CHARLES L. TALBOT, a

citizen of the United States, residing at Chicago, in the countyof Cookand State of Illinois, have invented certain new and.

useful Improvements in;,Loading Applinces, of which the following is aspecificatlOILI' My invention relates to street cleaning and othersimilar appliances and concerns more particularly an improved and novelstyle of apparatus for removing snow and the like from the street andloading it upon a truck to be carried away for disposal.

The new structure is intended toprovide a complete snow handlingmachine, but its essential parts may be made as an accessory for streetcleaners which remove the ordinary dirt and filth from the pavements,thus giving to such cleaners a capacity 'for operating efficientlythroughout the entire year. The prime purpose and leading object of myinvention is the provision of such a structure which is simple inconstruction, which operates efficiently, which isunlikely to becomeinjured or damaged in ordinary service, which. is easily operated andcontrolled, and which may be produced and maintained in proper conditionat relatively small expense. i

To the attainment of, this and other desirable ends, the scoopassociated with the elevating conveyor is located at the frontend of themotor driven vehicle whereby the appliance may be driven over a pavementand remove the snow ahead of it and whereby it may be readily brought toa pile of. snow and cause'the'latter to be removed, elevated, anddelivered into a waiting truck.

It is not necessary that the truck back up to the snow loader, butrather it may be drawn up to the side of the latter and receive itsload; in fact, the loader is designed to deliver the snow to either sidethereof thus permitting the loading of trucks from both sides.-

In order that those skilled in this art may have a full and completeunderstandmg of the invention and its several advantages, in theaccompanying drawings forming a part of this specification I haveillustrated apreferred embodiment of such invention and like referencecharacters have been used throughout the several views to apply to thesame parts of the mechanism.

Figure 2 is a plan view of the same;

Figure 3 is an enlarged vertical section on line 33 of F igure 1; A

Figure 4 is a fragmentary detail of a portion of the transverseconveyor;

Figures 5, 6, and 7 are details of the elevating conveyor; and

Figures 8 and 9 are details of the structure for adjusting the crossconveyor to cause it to be operative at either side of the appliance. I

It is intended, although the invention is not so limited or restricted,to use a street cleaner of substantially the type and style set forth inUnited States Patent 1,239,293, J. M. Murphy, Street Sweeping Machine,granted September 4, 19-17 and to so modify it or removesome of itsparts whereby it may receive and operate the snow handling attachment oraccessory.

Accordingly, the appliance of the present application includes amainframe 20, two rubber-tired front carrying wheels 21, 21, a rearsimilarly tired steering wheel 22, steering mechanism 23,.a steeringwheel 24,

.an internal combustion motor 25 associated with the usual gearingcontained in a housing or gear box 2 a drive shaft 27 equipped withsprocket-w eels and chains 28 for rotating the drive wheels 21, 21, aseat 29 for the operator, and a dirt receptacle or storage compartment30 substantially like the corresponding parts of the machine of thepatent referred to, the other elements of the street sweeper beingremoved to accommodate and operate the snow handling structure about tobe described in detail.

A suitably-shaped, upright. frame, denominated as a whole 31, isremovably or demountably bolted or otherwise conveniently fastened tothe center portion of the mainframe 20, and supported in part by suchsupplemental or auxiliary frame and in part by the dirt receptacle 30,to which it may be fastened in any convenient manner, there stretches ofendless sprocket chains 36, 37,

which at intervals have suitable lugs or ears 38to which are fastenedtransverse blades 39, 39 each strengthened and stiflened by a truss-rod40 appropriately connected to the end portions of the blades andequipped with central struts 41.

At their upper ends these chains encircle sprocket-wheels 42 on a shaftmounted in bearings carried by the frame 31, and at their lower endsnear the ground such chains pass around similar spaced sprocket wheels43 on a shaft 44- revolubly mounted in a pair of arms 45, 45 fulcrumedon the inclined frame 3% at 46 with weights 47 on their other ends, suchconstruction permitting of anupward movement of the shaft andsprocket-wheels under abnormal conditions hereinafter referred to.

The shaft' of the upper sprocket wheels is rotated from the power shaft27 through suitable sprocket-wheel and chain connecside plates tions 110and 111 and an intermediate cross shaft 112.

The sloping lower members 48, 48 of the frame 32 have cross boards 49secured thereto, and to prevent wear these are covered with sheet-metal50, the edge portions of which are bent upwardly or flare outwardly at,51'b'eneath the lower tracks 34 as is indicated in Figure 5.

To confine the snow above such tracks and prevent its spilling, as it ispushed upwardly by the traveling blades 39, opposite metal 52, 52 arefastened to the framework, whereby the plates 50 and 51 in com binationwith the plates 52 conjointly form an inclinedor sloping trough for theaccommodation of the upwardly traveling snow. I v

At the bottom of the sloping or inclined frame'32 and below the lowerend of the bladed sprocket-chains, I provide a hinged scoop 53 havingabottom wall 54 and flaring side walls 55 shown most clearly in Figure2.

Such scoop or shovel is hinged at 56 on the lower end of the inclinedframe and it has. two arms 57, 57, one at each side, extended beyond thehinge pins and supplied with adjustable weights 58, 58.

To adjust or-govern the position of such scoop or shovel, it is equippedwith an outstanding pin 59 just above'one arm of a bell-crank 60fulcrumed at 56, the other arm being connected by a link 61 to anotherbellcrank 62 pivoted on the frame 32 and connected by a link or rod 63to an operating or controlling handle or lever 64 fulcrumed on the frame31 in convenient position to be actuated by the occupant of seat 29.

The scoop normally overbalances the action of the weights and itsposition can be easily regulated by manual actuation of the handle, anysuitable locking means, not

blades to efficiently and effectively perform I the function specified.

Such blades also may be used to wear away or break down a pile of snowinto the scoop from which it is carried up as indicated.

On the frame 31 a cross conveyor is mounted and so constructed that itmay deliver its load to either side of the appliance.

Such conveyor or carrier comprises a pair of spaced, endlesssprocket-chains 70, 71, passing around sprocket-wheels 72 and 73 mountedonsliafts 74 and 75 supported in bearings 76 and 77 on the opposite endsof an adjustable frame 7 8 adapted to'slide during its adjustmentcrosswise the framework 31 on a plurality of anti-friction rollers 79.

The upper stretches of these companion chains are driven by a pair ofsprocketwheels 80, one for eachchain, located below the upper portion ofthe chain as shown in Figure 3, and in cooperative relation therewith,whereby the turning of the sprocket wheels causes the usual travel ofthe chains in either direction depending upon the control mechanismdescribed below.

To hold such portions of the chains down in proper position withrelation to the driving sprocket-wheels, 81, 81 supported on the frame31 as depicted in Figure 3.

The two sprocket wheels 80 are on a suitably-supported shaft 82 equippedwith a sprocket wheel 83 driven by a sprocketchain 84 operated by asprocket-wheel 85 on a shaft 86 supplied with a friction cone 87 adaptedto be rotated by either one of a pair of similar cones 88 and 89slidable on and rotated by a shaft 9 driven from the shaft 27 through asprocket chain 91 co-acting with sprocket-wheels on the two shafts inthe usual way.

I employ idler rollers The friction cones 88 and 89 are adapted to heslid along on shaft 90- by an enclosing frame 92 operated by a leverhandle 93 connected thereto by a link 94.

Thus by means of such controlling handle, the direction of travel of thehorizontal chains may be reversed at will.

In order to constitute such chains as a belt conveyor to carry. the snowor other material crosswise the ,machine after receiving it from theelevator, many of the links of the chains are provided with lugs or ears95 to which the marginal portions of flexible belt 96 are fastened, thelading, of course, being supported and transported by the belt pro er,the chains on opposite sides thereof constituting the driving means forthe belt.

To enable the operator to shift, or modify the position of thetransverse frame and such belt conveyor carried thereby, to dischargeits load at will at either side of the appliance, I provide thefollowing specified cooperating lnstrumentalities.

- a waiting truck, as indicated conventionally On the supplemental frame31, I mount a shaft 100 and equip it with a turn wheel 101 whereby theshaft may be manually operated.

On the shaft I provide a drum 102 associated with two cables 103 and 104each having an end fastened to the drum and their other ends securedto-the opposite end portions of the sliding frame 78, whereby by turningthe handle or wheel 101 one cable will be wound up and the other paidout from the drum causing a corresponding sliding movement of the frameand the conveyor which it carries.

Turning the wheel and shaft in the other direction will, of course,cause the sliding ofthe frame and its conveyor in the oppositedirection, thus enabling the operator to deliver the load to either sideof the ma.- chine as he chooses. If desired, two drums 102 may beemployed on the shaft 100 and two sets of cables used, one for each sideof the slidable or reciprocatory frame.

In operation the machine is caused to travel along the pavement or itmay be advanced to a pile of snow, and in either case the scoop incombination with theblades on the elevator chains causes the upwardtravel of the snow in the inclined chute, from which it is automaticallydelivered on to the transverse conveyor apron which transports itsidewise and delivers it over its end into in dotted lines in Figure 3.

The position of the scoop for most effective work is controllable by thehandle or lever 64 and the scoop is free to rise if it encounters anobstruction, being automatically returned to adjusted position by reasonof the fact that'its weight overbalances the action of the Weights 58,:as soon as this action is permitted.

In case any of the blades 39 in traveling around the lower sprocketwheels engage any large hard and resisting object such as a rock orpiece of ice, such sprocket-wheels and their mounting yield upwardly byreason of the weighted structure employed and prevent breakage of any ofthe parts.

It will be seen, therefore, that the appliance described in detail aboveand illustrated in the drawings fulfills all of thespecified advantagesand overcomes a need foranapparatus of the structure and operating'inthe manner indicated.

The invention is not limited and restricted to the precise and exactdetailsof construction since it may be modified within coinparativelywide limits without departure from the heart and essence of theinvention and without the sacrifice of any-of its substantial benefitsand advantages.
